Nothing new in this version besides reliability improvements and that it now works with the newly released Silverlight 2. The team is focusing on improving existing features as they are getting close to wrapping up work on version 1 of this powertoy. Details on some of those under the hood changes will be posted on their Blog in the upcoming months.

As you already know, via the Deep Zoom Composer you can upload to PhotoZoom, so this site has also been updated to work with the new Silverlight 2 release.
